The 1968-1969 Plymouth Sport Satellite and GTX spanned a broad engine lineup: everything in the Chrysler cupboard from 225 Slant Six to the amazing Street Hemi -- still jokingly rated at 425 horses -- and the GTX's standard 375-horsepower "Super Commando" 440.

Sport Satellites started with a mild 230-horsepower 318 and ended with optional 383 V-8s packing 300 or 330 horsepower. All rode a typical Chrysler chassis with acclaimed torsion-bar front suspension and available power front-disc brakes.

Most 1968 "Bs" carried extra-cost TorqueFlite automatic in lieu of manual three-speed, but GTXs included TorqueFlite and offered four-on-the-floor as a no-cost alternative.

As before, GTXs also included stiffer suspension and heavy-duty rear axle with "Sure-Grip" limited-slip differential. Identifying the 1968s outside were special striping, bold GTX nameplates, and a "performance" hood with twin outward-facing dummy air intakes (shared with Road Runner). Featured inside were front buckets, console, and pseudo-wood trim.

Though Plymouth still lagged far behind Chevy and Ford in sales, its 1968 total of nearly 750,000 was a gratifying gain of some 111,000 over 1967. Significantly, intermediates accounted for about a third. Satellite was the volume leader by far, but non-wagon Sport Satellites managed around 22,500 and the two GTXs close to 19,000.

Predictably, the 1969s changed mainly in trim and appearance details, but speed freaks delighted in a monster 440 with three two-barrel carburetors. It was dubbed, naturally enough, "440 6-bbl."

Allegedly making 390 horsepower (and probably far more), it was a new option for the Road Runner, as was a functional "Air Grabber" hood and five special Performance Axle Packages. But the GTX got only the last; worse, its center console now cost extra.

Optional on the GTX was the fearsome 426 Street Hemi, conservatively rated at 425 horsepower.

Though performance remained formidable-under 6.5 seconds 0-60 with the Hemi and automatic, a half-second more with the 440-the GTX was being shoved out of the spotlight by the cheaper "Beep Beep" car. Sales accordingly withered to 15,000, while Road Runner soared beyond 84,000. Sport Satellite improved, too, a new four-door sedan boosting 1969 volume to near 29,000.

The once-inspiring GTX would vanish two years later, while Sport Satellite, not all that special anyway, would simply be lost in a crowd of faceless family intermediates. Sad to say, Plymouth let its carefully cultivated garden of the 1960s become a weed patch in the 1970s. You know the rest.
